[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0035] Please refer to the attached document. Figures 1-4 This application provides an airbag assembly 100, which is applied to a seating chair and is used to support the user's back.

[0036] Please refer to the attached document. Figures 1-2 In this embodiment, the airbag assembly 100 includes a seating chair body 10 and an airbag module 20. The seating chair body 10 has a backrest 11 for the user's back to contact. The airbag module 20 is connected to the backrest 11 and includes an airbag support 21. The airbag support 21 expands in the working state and forms a back support space for the user's back to lean against. As the airbag support 21 expands, the user's back moves closer to or further away from the backrest 11. The airbag support 21 supports the user's back in the expanded state and moves the user's back, thus achieving traction of the user's back by the airbag support 21. This allows the seating chair body 10 to integrate the traction effect on the user's back through the airbag module 20, avoiding the seating chair body 10's inability to traction the user's back and improving the support effect of the airbag assembly 100 on the user's back.

[0037] Please refer to the attached document. Figures 1-2 In this embodiment, the main body 10 of the seating chair serves as a supporting component of the airbag assembly 100, and the main body 10 of the seating chair is used to support the airbag module 20. The main body 10 of the seating chair is provided with a backrest 11, which is used for the user's back to contact; so that the backrest 11 can support the user's back, thereby ensuring the user's posture during use and thus reducing the user's fatigue.

[0038] Please refer to the attached document. Figures 1-4In this application, the airbag module 20 is connected to the backrest 11. The airbag module 20 includes an airbag support 21, which expands in the working state to form a back support space for the user's back to lean against. As the airbag support 21 expands, the user's back moves closer to or further away from the backrest 11. The airbag support 21 supports the user's back in the expanded state and moves the user's back, thus realizing the traction of the user's back by the airbag support 21. This facilitates the integration of the traction effect of the user's back by the airbag module 20 into the main body of the chair, avoiding the inability of the main body of the chair to traction the user's back and improving the support effect of the airbag assembly 100 on the user's back.

[0039] Please refer to the attached document. Figures 3-4 The airbag support 21 is built into the backrest 11 so that the airbag support 21 can be fixed to the inside of the backrest 11, thereby facilitating the surface protection of the backrest 11 for the airbag support 21, preventing the airbag support 21 from being easily cut by external parts, and extending the life of the airbag support 21.

[0040] Alternatively, the airbag support 21 can be positioned on the surface of the backrest 11 to facilitate direct contact between the airbag support 21 and the user's back, thereby improving the user's back comfort. When air is introduced, the airbag support 21 expands outwards, supporting the user's back and moving it, thus providing traction. This allows the main body of the chair 10 to integrate traction for the user's back through the airbag module 20, preventing the chair body 10 from failing to provide traction and improving the support effect of the airbag assembly 100. When air is deflated, the airbag support 21 contracts inwards, approaching the backrest 11 in its contracted state to relax the user's back, preventing the user's back from being constantly under traction and improving user comfort.

[0041] Please refer to the attached document. Figure 3 The airbag support part 21 is arranged in an arc or elliptical shape and is adapted to the user's back so that the user's back can fully fit the airbag support part 21, which improves the fit between the airbag support part 21 and the user's back and ensures the user's comfort.

[0042] Please refer to the attached document. Figure 4The airbag module 20 also includes an air pump 22 and an air tube 23; both the air pump 22 and the air tube 23 are connected to the backrest 11 so that the air pump 22 and the air tube 23 can be fixed to the backrest 11. The air tube 23 connects the air pump 22 and the airbag support 21. The air pump 22 inhales or exhales air from the airbag support 21 through the air tube 23 so that the airbag support 21 can expand or contract through the air pump 22 and the air tube 23. As the airbag support 21 expands, the user's back moves closer to or further away from the backrest 11. The airbag support 21 supports the user's back in the expanded state and moves the user's back, so that the airbag support 21 can traction the user's back. This makes it easier for the main body of the chair 10 to integrate the traction effect on the user's back through the airbag module 20, avoiding the inability of the main body of the chair 10 to traction the user's back and improving the support effect of the airbag assembly 100 on the user's back.

[0043] Please refer to the attached document. Figures 2-4 The airbag module 20 also includes a controller 24, which is electrically connected to the air pump 22. This allows the controller 24 to adjust the air pump 22's exhaust. The controller 24 is connected to the main body 10 of the seating chair and exposed to the external environment, allowing the user to operate the controller 24 in the external environment. This enables the user to control the air pump 22's exhaust through the controller 24, allowing the airbag support 21 to adjust the traction force and duration on the user's back, thus ensuring user comfort.

[0044] Please refer to the attached document. Figures 1-2 The controller 24 is located on the outside of the airbag support 21. Both the controller 24 and the airbag support 21 are connected to the main body 10 of the seating chair, so that both the controller 24 and the airbag support 21 are fixed on the outside of the main body 10 of the seating chair, thereby making it convenient for the user to operate the controller 24 in the external environment to expand or contract the airbag support 21.

[0045] Please refer to the attached document. Figure 4 The airbag module 20 also includes a telescopic part 25, which is located between the airbag support part 21 and the backrest part 11 and extends and retracts relative to the backrest part 11 in the front-back direction, so that the airbag support part 21 can expand or contract relative to the backrest part 11 through the telescopic part 25, thereby making it easier for the user's back to move closer to or further away from the backrest part 11 as the airbag support part 21 expands.

[0046] Please refer to the attached document. Figure 4The telescopic part 25 is connected to the airbag support part 21 and extends as the airbag support part 21 expands. The airbag support part 21 supports the user's back in the expanded state and moves the user's back, so as to realize the traction of the user's back by the airbag support part 21. This makes it easier for the main body of the chair 10 to integrate the traction effect of the user's back through the airbag module 20, avoiding the inability of the main body of the chair 10 to provide traction for the user's back, and improving the support effect of the airbag assembly 100 for the user's back. The telescopic part 25 is a flexible telescopic component.

[0047] Please refer to the attached document. Figure 3 The airbag support 21 has multiple parts, all of which are connected to the same backrest 11. By arranging multiple airbag support parts 21, the traction force of the airbag support parts 21 relative to the user's back is increased, thereby improving the traction effect of the airbag support parts 21 relative to the user's back. The multiple airbag support parts 21 are used to contact different positions on the user's back and expand or contract synchronously, so that the multiple airbag support parts 21 can traction multiple different positions on the user's back, ensuring that the user's back is fully covered.

[0048] In another embodiment, a seating chair includes an airbag assembly 100, which is part of the seating chair used to adjust the contact point between the human body and the seat to obtain a more comfortable angle to reduce user fatigue.

[0049] At this time, the airbag assembly 100 includes a seating chair body 10 and an airbag module 20; the seating chair body 10 is provided with a backrest 11 for the user's back to contact; the airbag module 20 is connected to the backrest 11, and the airbag module 20 includes an airbag support 21. The airbag support 21 expands in the working state and forms a back support space for the user's back to lean against; the user's back moves closer to or further away from the backrest 11 as the airbag support 21 expands. The airbag support 21 supports the user's back in the expanded state and moves the user's back, so as to realize the traction of the user's back by the airbag support 21. This makes it easier for the seating chair body 10 to integrate the traction effect of the user's back through the airbag module 20, avoiding the inability of the seating chair body 10 to traction the user's back, and improving the support effect of the airbag assembly 100 for the user's back.
